By solving the quadratic equation using completing the square method we got that Penelope should have added 4 to both sides instead of adding 1.
<h3>What is quadratic equation ?</h3>
Any equation of the form 
where x is variable and a, b, and c are any real numbers where a ≠ 0 is called quadratic equation .
Given work of Penelope is
Now we can see that Penelope determined the solutions of the quadratic function by completing the square. so he must have been done as following
By solving the quadratic equation using completing the square method we got that Penelope should have added 4 to both sides instead of adding 1.

The given equation is an equation of a circle where the number after the equal sing is the radius squared.
To find the radius take the square root.
Radius = SQRT(169)
Radius = 13 units.
Just make a triangle and an X and Y axis and reflect it over the Y axis. It's that simple. Then tell how you did it. Obviously it will be a reflection. Name the points (before and after) and you are done.

Answer:
d.every word in the first sentence of the first page of every chapter.
Step-by-step explanation
- the sample space means the set of total possible outcomes or ALL possible outcomes.
- so here, the situation is about the teacher reading a sentence.
- the favorable outcome is the set which has all the words that the students would not know from all the words read by the teacher or simply from the sample space.
- since the teacher reads the first sentence on the first page in every chapter , all the words in that sentence will be sample in this situation.
